Re: [platform-swt-dev] FW: Running SWT on Mac OSX

["Allan Wick" <registerit@xxxxxxxxxxxxxx>]

Andre,

Thanks for the information.

The problem is that I am not doing development on the Mac.  I don't even own
one (Gasp :).  I am trying to port my application to the mac using a friends
computer.

Can I get a script where I can plug my application variables into it or are
the scripts different for different machines?

Thanks,

-Al
